Hierarchical dendrogram using Ward’s clustering method (a), and PLS-DA regression score plot (b), correlation circle plot (c) and loading plots (d, e) of anthropogenic disturbance parameters on seasonal roost patterns. The score plot visualises the component scores, and prediction areas of each roost category. The correlation circle plot displays the Pearson correlation between the variables and latent components. The loading plots show the loading weights (contributions) of each variable on each component. The most important variables (according to coefficient values) are ordered from bottom to top. Colours indicate the seasonal roost pattern where the mean value of this variable is maximal. Roost Height: roosting height; Light: light intensity; Noise: noise level; DistRoad/DistTree/DistLight/DistBuild: distance to the nearest road/tree/light/building
